For a message to pass DMARC authentication, it must pass SPF authentication and SPF alignment and/or pass DKIM authentication and DKIM alignment. There is another scenario in which SPF/DKIM alignmentcan pass even if the domains are not identical. DMARC is implemented by publishing a policy as a TXT record in DNS and is hierarchical (for example, a policy published for contoso.com will apply to sub.domain.contoso.com unless a different policy is explicitly defined for the subdomain).
